Claims.

My invention relates to spinning and twisting frames of the ring type, and pertains particularly to the ring holders used on such frames.

The spinning and twisting rings used are of 5 two general types, those having horizontal flanges for receiving the traveler, and those having vertical flanges for receiving the traveler. The rings are made of very hard and finely polished steel, and are commonly mounted in metal holders which in turn are secured to the ring rails extending along the sides of the frame. The ring rails are providedwith openings or passageways and 'the ring holders are aligned therewith so that the spindles or bobbins may be moved upwards and downwards through the rings to effect the winding of the thread or yarnthereon.

Since the size of therail openings required for the horizontal ring type differs from the size required for the-vertical ring type, various'forms of universal ring holders suitable for mounting on the ring rails and holding either type ring, as desired, have been devised, in order to obviate thenecessity for reboring the ring rails or for replacing same. The rings themselves, however, due to manufacturing conditions and particularly the hardening process they are subjected to, are not of uniform size or of uniform curvature, and difiiculty has, therefore, been found in properly seating and locking the rings in the holders. It is the principal object of my invention to devise a universal ring holder adapted to hold either horizontal or vertical rings, and to firmly and snugly gripthe rings despite slight variations in 'size' and. curvature thereof.

A further difficulty-in the use of universal ring holders has resided in the need for supplying lubrication to vertical travelers. The present con- .struction comprises use of separate lubricant containers mounted on the ring rails, and communieating with the'ring holders and rings, thus necessitating drilling of the ring rails and resulting in further weakening thereof. It-is, therefore, an additional object of my invention to provide a holder adapted to house and to supply lubricant, thus simplifying mounting and eliminating the use of separate containers.

With the above and other objects and advantageous features in view, the invention comprises a novel arrangement of parts more freely disclosed in the detailed description following, in conjunction with the accompanying drawing, and more specifically defined in the claims appended thereto.

In the drawing,

substantially constant.

' Figure 1 is a plan view of the novel holder, with a vertical type ring mounted therein,

Figure .2 is a fragmentary section therethrough in the line.2-2 of Figure 1,

Figure 3 is a fragmentary section showing the holder used for a horizontal type ring,

Figure 4 is a view of .a modified form of holder, suitable for mounting in a ring rail opening, and Figure 5 is a fragmentary sectionthereof, on the line 5-5 of Figure 4.

Referring to the drawing, the novel ring holder 10 is made of metal, preferably cast aluminum or cast iron, and is split as shown, the two ends terminating in laterally extending bosses 11, 12 which are threaded to receive a lock screw 13. The rail lock extensions 14, 15 are provided, diametrically oppositely disposed as shown, with slots 16, 17 for receiving screws or bolts for locking the holder to the frame rail A.

The ring holder has an annular projection or rib 18 upon which the flange 19 of the vertical ring 20 rests, the latter having a vertical traveler 21 of standard type positioned thereon. As shown in Figure 1, anoil cup 22 is formed laterally of the holder to contain lubricant and a lubricant retainer such as gauze -or felt pads .or the like, the oil cup communicating with the ring, through a radial channel 23; the preferred lubricating system includes a wick 24 which has one end secured in the oil cup, passesthrough the channel 23, and is then threaded or otherwise secured in an oil groove 25 in the ring, this groove in turn communicating with the traveler oiling groove 26 by means of suitable passages or cuts. Threading of the wick alternately through the oil groove 25 and the oiling groove 26 is preferable, as the inner edge of the traveler then rides over exposed oil containing wick portions. If desired the novel holder may be formed without the oil cup andcommunicating groove, as many types of rings are not lubricated.

The holder 10,is resilient in order to snap over the ring and frictionally retain. it in place, but the closing of the bosses 11, 12 by the lock screw 13 insure a snug, tight grip, and tends to overcome slight warping of the ring, thus correcting slight changes of curvature and reducing uneven tension on the yarnor thread and resultant thick and thin portions, and keeping the driving force The use of the above holder construction also permits a thirmer holder as the grip on the ring is not due to resilience alone, but is positively obtained; it is thus feasible to use a ring of greater diameter.

The substitution of a horizontal ring in place of a vertical ring is readily made, see Fig. 3, as it is merely necessary to loosen the lock screw 13, take out the vertical ring, insert a horizontal ring such as 27, equipped with a horizontal .traveler 28, to rest on the rib 18, and tighten the lock screw 13 to firmly grip the lower flange of the horizontal ring, and thus lock the ring in place.

The novel construction may be applied to holders of the type designed for insertion into ring rail openings, as shown in Figures 4 and 5. These holders, designated 29, are usually split to receive the rings 30 equipped with travelers 31, and may be formed as shown in Figure 5 to receive either horizontal or vertical type rings as referred. The upper portion of the holder is provided with laterally extending bosses 32, 33 adjacent the split, and a lock screw- 34 for forcing the bosses,

larger ring and a larger bobbin, as the positive grip compensates for decrease in or lack of resilience of the holder.

It is desirable in certain installations to bore the holder large enough so as to readily receive the ring when the bosses are in unlocked, spaced relation; the ring may then be dropped loosely into the holder, and the lock screw tightened to firmly lock the ring in place. This construction facilitates insertion of the ring, and removal thereof for cleaning.

The novel holder is thus simple to install, is

self adjusting to accommodate rings of slightly different diameters, and eliminates the deleterious efiects resulting from slight warping of the ring; the use of an integral lubrication supply, when desired, simplified installation and operation. The term split ring holder, as used in the claims, designates an annular ring holder that is radially split at one section to permit resilient lateral movement of the holder ends.

While I have described specific constructional embodiments of my novel ring holder, such changes in design, in size, and in arrangement and proportion of the parts may be made as are deemed advisable for accommodating different types of rings, within the spirit and the scope of the invention as defined in the appended claims.-

I claim:-

1. In combination, a split ring holder adapted to be seated on a ring rail, a ring holding flange on said ring holder, a ring seated on said flange,

an annular oil groove in said ring, a wick in said oil groove, an oil reservoir in said holder, said holder having a communicating passage communicating said reservoir with said ring oil groove, and means engaging the split ends of said ring holder for locking said ring in said "holder,

2.
